eufyCam 3 (S330)

Based on 41 comments across 4 communities
TL;DR
Many owners report that HomeBase 3 firmware updates broke their cameras, killing notifications and motion detection until Eufy pushed another fix, only for the problem to keep coming back. Batteries dying suddenly, units going offline and refusing to re-sync, and weak, slow solar charging are the other big complaints, with several people switching to external panels or USB power to keep cameras alive. The 4K picture and no-subscription local storage are genuinely well liked, but enough owners hit serious reliability failures that this is a real concern, not a minor one, and many regret the buy.

29% of 41 verified owners recommend the eufyCam 3 (S330).

Second, the EufyCam3 is a PIR sensor to limit battery usage. Per the instructions it can be 7-10 ft off the ground and aimed 5 degrees down. It will detect horizontal motion for about 25-30 feet out.

That is big reason I went with eufycam3 since it had solar panels, battery, spotlight, and 4K for $200. When I thought it was fully local, it seemed like such a good deal.

Try Homebase3 Bro, Works fine in and around my House with one Home Base. Camera is EufyCam3/S330. Activate the Beta Mode (more power) in the options

I have a Eufycam 3 (S330) which also has an integrated panel). It is also shaded, and I was only getting a few mAh of charge every day. Going to an external power source was the solution

The recent HB3 firmware update is what caused the the issue for me. It’s incredibly frustrating having non functional cameras and no helpful support from Eufy.

strongly recommend the EufyCam 3 / S330 Solar powered group. About €1k euro for 4 cameras and a Home Station but set up is easy, no electrics to worry about and for me at least have been extremely reliable.

EufyCam 3 motion seems pretty terrible. I don't know if it is something they can improve with a future firmware update or not.

Our internet was out for a day and I can confirm, after messing with the system a bunch, that you CAN in fact access your local storage and live-stream your cameras and doorbell thru the app. Note: My setup is Homebase 3 with 3 EufyCam3's and 1 Eufy Doorbell 2K, all wireless.

I have the eufycam3 4k wifi cameras, they have built in solar panels so as long as you mount them where they can sunlight they never need recharging. I'm happy with them so far.

Have 2 eufycam3. When first set up they were perfect, but I think since last update it's been missing events.

Reddit▲ recommend

Installed 5 of them a tad over 2 years ago and have not needed to charge them even with highest sensitivity for motion detection, all thanks to the built in solar panels.

I have 4 of them plus doorbell dual and nothing is available for homekit. I tried going through home assistant and home bridge but nada. Best I can do is to get snapshots in apple home.

Overall, the EufyCam S330 is a solid but imperfect option if you want a wireless outdoor camera that runs on solar, records in 4K, and doesn't hit you with subscription fees.

I’m returning the EufyCam3 kit anyway, gonna get the E330 camera kit. I guess 24/7 recording is worth it.

I plugged in the Eufycam 3 (S330) with USB using it as indoor camera where there is no direct sunlight. It is still 100% power after 5 days.

Best wireless battery cameras I’ve seen on the market, in terms of picture quality and install/set up.

FIXED My Homebase 3 updated to v3.1.9.1 overnight which seems to have fixed my problem. I’m Getting notifications again for my S330 cams.

but my EufyCam3 refused to take a charge from an external panel for some unknown reason.

I've been using the EufyCam3 and Solo S340 without HomeBase3 for a while now, and let me tell you, the AI performance at night is pretty decent. It does a solid job of distinguishing between people and pets. I've had instances where it's alerted me about someone lurking around at night, and it turned out to be accurate.

Customer support was good about it, and sent a replacement.

I wouldn't have gotten this deep into the Eufy ecosystem knowing how bad it was, but I'd already made a large investment into the ecosystem (based on highly biased internet and YouTube reviews) prior to experiencing the truth for myself. And yet I still haven't found a *wireless* security camera platform with better offerings for the price.

Mine likes to save a bunch and then machine gun them. -_-

Excellent 4K video quality, offline recording, facial recognition and even the option for AI detection with people, animals and vehicles – the Eufy S330 eufyCam has it all.

For me the wifi between the camera and homebase is weak, so everything gets delayed (recording and notifications) and there’s no way to make it better, so I kinda hate mine
